Abstract

With the rapid improvement of user-side multi-energy load demand response ability, how to effectively use the demand response variation to realize the optimal scheduling of integrated energy system has become the main research direction. An optimal scheduling model of integrated energy system based on power and gas interconnection considering demand response is proposed in this paper. Firstly, the scheduling framework of the integrated power and gas energy system is constructed, and the demand response participation scheduling method is analyzed. Secondly, the natural gas network and the key coupling equipment of power and gas are modeled. Based on the idea of virtual power plant, the equivalent unit output model of incentive demand response is established, and the optimal scheduling model of integrated power and gas energy system considering demand response is further constructed to formulate the optimal scheduling scheme of integrated energy system (IES). Finally, an example shows that the proposed strategy can effectively improve the clean energy consumption rate of IES and reduce the overall operation cost of the system.
